part of the upper lip. It is semi-lanceolate with a straight fore-edge. The lateral line de+ 
scends a little at its commencement, and when opposite to the acute tip of the pectoral, takes 
a straight course along the middle of the height to the tail. It is traced on thirty-six scales, 
and there are nine rows of scales in the height of the body, of which five are above the lateral 
line. The dorsal commences a little before the middle of the length, caudal excluded, and 
its height, which is equal to two-thirds of the height of the body, measures almost twice the 
length of its base. The last ray being comparatively longer and the corners of the fin rounded, 
it has not the triangular form of the dorsal of many of the other Leucisci. The front of 
the ventrals is under the middle of the dorsal, and the anal is midway between them and the 
caudal. 
The large discs of the scales, down to a row beneath the lateral line, have an uniform oil- 
green tint with much lustre, and are surrounded by a defined border of deep duck-green, pro- 
ducing hexagonal reticulations. Lower down, the discs of the scales are silvery, and the 
meshes that enclose them pass into ochre- and cream-yellows. The base of the pectoral and 
scales before that fin have a red-lilac tint, and the head corresponds in colour with the body, 
being green above and ochraceous or cream-coloured below. There is a little blue around 
the eye and on the upper corner of the operculum. The pectorals are green, with a brownish 
gloss; the ventrals buff-coloured, and the other fins dark greenish-gray, the rays of the caudal 
being dark green. In the figure belonging to the collection in the Banksian library quoted 
by M. Valenciennes, the bases of the scales are darker than the borders, but the drawings are 
otherwise so much alike as to occasion little doubt of their being representatives of the same 
species.

Chinese name, Hih hwan, “ Black hwan fish” (Birch); Hih wan, “ Black 
—” (Reeves); Hak wan (Bridgem. Chrest. 233). Length of the 
figure 153 inches. Height of body 3 inches. Length of head 33 inches. 
This fish is elongated like idelia, but is rather less symmetrical, has even a thicker tail, 
more obtusely-forked caudal, and more unevenness in the profile of the head and shoulders. 
The mouth is similarly formed, the eye in the same position, and the fins similar in place and 
form. Thescales are smaller but appear to be equally strong, and the lateral line as distinctly 
marked by an elevated straight tube on each scale. It runs very nearly straight, or with a 
slight general decurvature along the middle of the fish. The fins are taller than those of 
jesella, the dorsal being equal in height to the body, and the anal not very much lower. All 
the fins are obtuse. The operculum and supra-scapulars are furrowed. 
General colour pitchy or blackish-brown, deepest on the back, and gradually changing on 
the belly to bluish-gray. The scales are not enclosed in a dark mesh-work like those of 
jesella, but are darkest on the fore-edge, and grow gradually paler towards their bases. Head 
blackish-gray above, beneath white. There is a greenish tint on the breast and a tinge of 
crimson along the edge of the belly. All the fins are blackish-gray, deepening to black to- 
wards the edges, and their rays are whitish at the base. There are forty-three scales on the 
lateral line, and ten or eleven rows in height. The rays shown are D. 9; A. 10, &c.

Chinese name, Hwang we ling, “ Yellow-tailed carp” (Birch); Hwang

11 inches. Height of body nearly 3 inches. Length of head 1:8 inch. 
Genus Aspius ?, Agassiz. 
This figure represents a fish with an elevated back rising to a point at the beginning of the 
dorsal. The anterior slope is varied by a moderate gibbosity of the nape, but the posterior 
one runs in a perfectly straight, obliquely-descending line to the caudal fin. Belly most pro- 
minent under the middle of the pectorals, sloping suddenly up to the throat and very gradually 
to the caudal. Head small. Eye large and low in the cheek. Snout full and apparently 
fleshy, projecting beyond the lower jaw, which shuts up beneath it. Pectorals small, acute. 
The dorsal commences in the middle of the distance between the top of the snout and base of 
the caudal, and its second ray is represented as stout, round, and acute, like that of a Rhodeus, 
* the third one being also simple, but more slender and shorter. D. 3|6, last divided to base ;
